The woman, Talisa Coombs, told Delaney she’d just gotten into what she alleged was a physical altercation with her granddaughter’s mother, Maria Pike, and called 911. Independence police’s response to that 911 call ended with the shooting death of Pike, 34, and her two month old daughter, Destinii Hope — who were identified Tuesday by authorities from the Police Involved Investigative Team, or PIIT, a team of eastern Jackson County detectives called in to investigate police shootings and use-of-force incidents.
